Hello,

I've got a setup where two different external networks are presented to openstack instances. Since the external networks are on different interfaces and have different purposes, I've set up two different L3 agents, each configured to handle a specific external network following these directions: http://docs.openstack.org/admin-guide...

With both agents running I can create routers (the namespaces do show correctly, including ip address assignment), but whenever I add a port to an internal subnet I get the following error on neutron-server.log:

The result is that instances inside the networks cannot reach the router (nor can I ping instances from inside the router namespace). The router's public address, however, works just fine.

The configuration files for the agents are:

My neutron.conf looks like this: http://pastebin.com/5Yinmfnz

UPDATE: I have given up on the "host" parameter on the L3 agents. With this I do not have port binding errors but the agents occasionally stop responding until they are restarted.
